IMPROVEMENT IN PEN-HOLDER TIPS- Specification formin g part of LettersPatent No. 127,113, dated May 21, 1872.

Specification of an Improvement in Pen- Holder Tips, invented by DANIELM. Sonmns, of the city of Brooklyn, in the county of Kings and State ofNew York.

This invention relates to what are known as barrel-tube pen-holder tips,and consists in the novel construction of such tip of a single piece ofsheet metal, whereby its cost is reduced, partly by the reduction of thenumber of machines and mechanical manipulations necessary for itsproduction, and partly by its being enabled, without detriment to itsefficiency and durability, to be made of a quality of metal inferior towhat is necessary for the manufacture of its two barrels separately fromseparate pieces of metal, and whereby, also, greater stiffness of thebutt and security of the nib are obviated.

Figure 1, in the accompanying drawing, is an under-side View of apen-holder tip constructed according to my invention. Fig. 2 is acentral longitudinal section of the same. Fig. 3 is a nib-end View ofthe same. Fig. 4. is a plan of the sheet-metal blank of which the holderis produced. Fig. 5 is a plan, showing the blank doubled preparatory toits being rolled or swaged into tubular form.

The single piece or blank of sheet metal A B, of which the tip isformed, has the wider portion A, on one side of the transverse dottedline 0, of a length, width, and form to produce, when rolled up into atube, the outer shell a of the tip, and has the narrower portion B, onthe other side of the said line a, of a length, width, and shape toproduce, when rolled up into a tube, the inner shell 12 of the tip; or,in other words, the said blank has the said part A of the size and formof the one blank commonly provided to make the outer shell, and the saidpart B of the size and form of the other blank commonly provided to makeI the inner shell I).

The first operation necessary in the manufacture, after the blank hasbeen cut to the size and shape above mentioned, is to fold the plate onthe line 0, bringing the part B flat against the part A; and the nextoperation is to swage or roll the doubled blank into the form of a tube,which, being double, makes both the outer and the inner shell. Thissecond operation completes the tip.

What I claim as my invention, and desire to secure by Letters Patent,is-

The pen-holder tip made of a single blank of sheet metal, of aformsubstantially as herein shown and described, folded and formed into atube, as herein set forth. 1
